IN Brief:
- USPS and Amazon have agreed revised delivery terms.
- Amazon’s parcel volume through USPS is set to fall under the new arrangement.
- The change reflects continuing realignment in carrier-retailer parcel strategies.
USPS and Amazon have agreed revised parcel delivery terms, resetting part of one of the most closely watched relationships in the US delivery market.
Under the new arrangement, the volume Amazon routes through USPS is expected to fall by around 20% compared with current levels. That is materially less severe than some earlier expectations, but it still points to a reshaping of parcel flows between a retailer with an increasingly developed in-house network and a postal operator that remains important in areas where density, reach, or service economics favour mail-based infrastructure.
Amazon has invested heavily in its own transport and delivery capability over recent years, yet the USPS relationship remains valuable where the retailer wants broad national reach and flexible hand-off options. For USPS, the adjustment again underlines how exposed postal parcel volumes can be to changes in retailer strategy, contract structure, and the evolving balance between outsourced delivery and vertically integrated networks.
The revised deal is unlikely to settle the wider question of how much parcel traffic major retailers will continue to place with external carriers. It does, however, offer another signal that the next phase of the parcel market will be shaped less by headline growth and more by where volume sits, how it is priced, and which parts of the network remain economically difficult to replicate.
